Summary: Pillar[n]arenes, composed of benzene panels with para-methylene linkages, are symmetrical macrocyclic compounds. The planar chirality of each panel and its preference for chirality-aligned states make pillar[n]arenes attractive scaffolds for chiroptical materials with intense circular dichroism (CD) signals. Additionally, the dynamic nature of the chirality in pillar[n]arenes allows for time- and procedure-dependent alignment phenomena and response to chiral guests, providing molecular sensors.

Summary: Controlling and memorizing chirality are important in chemistry. Noncovalent interactions have been commonly used for chirality memory, but the memorized chirality can easily be erased by changing conditions. This study successfully transformed dynamic chirality into static chirality in pillar[5]arenes by introducing bulky groups through covalent bonds. The chirality was memorized by the introduction of bulky groups and the diastereomeric excess was amplified by crystallization. The resulting pillar[5]arenes exhibited excellent diastereomeric excess.

Summary: A strategy is proposed to control the layer stacking of imide-linked 2D covalent organic frameworks (COFs) by altering the synthetic methods. The variation of interlayer stacking significantly influences their chemical and physical properties, including morphology, porosity, and gas adsorption performance. COFs with ABC stacking show higher C2H2 capacity and selectivity, and can selectively remove C2H2 from gas mixtures of C2H2/CO2 and C2H2/C2H4.

Summary: This study investigates the use of pillar [6]arene derivative modified by long alkyl chains (P6A-C10) as a stationary phase for high-resolution gas chromatographic (GC) separations of xylene isomers, addressing the challenge of separating aromatic isomers in chemical and petroleum industries. The P6A-C10 column shows higher resolution and unique advantages compared to commercial HP-5, HP-35, DB-17, and PEG-20M columns. Quantum chemistry calculations reveal differences in non-covalent interactions with the P6A-C10 pillar framework, leading to specific selectivity for xylene isomers. Furthermore, the P6A-C10 column exhibits good repeatability.

Summary: In this study, porous phenolic pillar[5]arene crystals were used as a reaction space to promote and perturb the equilibrium between lactones and their corresponding polyesters. Immersion of porous pillar[5]arene crystals in liquid lactones induced ring-opening polymerization of delta-valerolactone and epsilon-caprolactone at room temperature due to the catalytic activity of phenolic hydroxy groups via hydrogen bonds and the preference of pillar[5]arene cavities for linear guests, forming pseudo-polyrotaxanes of pillar[5]arene and polyesters.

Summary: A metallosupramolecular polymer network (DSPy subset of SHP5@Zn) was constructed by hierarchical self-assembly of a double-armed pillar[5]arene host (SHP5), a ditopic guest (DSPy), and Zn2+ ions, with host-guest recognition and metal-ligand coordination interactions playing a crucial role. The DSPy subset of SHP5@Zn assembly exhibits reversible sol-gel transition properties in response to various external stimuli, making it an excellent candidate for constructing smart gels. In addition, it can be used as a highly selective dual-channel sensor for OH anions, facilitating the development of a convenient test kit for OH sensing.

Summary: In this study, a novel type of macrocycle-strutted coordination microparticle (MSCM) was constructed using pillararenes as the struts and pockets, which exhibited unique activities of fluorescence-monitored photosensitization and substrate-selective photocatalytic degradation. The MSCMs were prepared via a one-step solvothermal method and showed well-ordered spherical architectures, superior photo-physical properties, and photosensitizing capacity. The photo-catalytic behaviors of the MSCMs revealed marked substrate-selective catalytic mechanisms, attributed to the variety in the affinity of substrates toward MSCM surfaces and pillararene cavities.
